ASTM E1687-10(2014)

1.1 This test method covers a microbiological test procedure based upon the Salmonella mutagenesis assay of Ames et al (1)2 (see also Maron et al (2)). It can be used as a screening technique to detect the presence of potential dermal carcinogens in virgin base oils used in the formulation of metalworking oils. Persons who perform this test should be well-versed in the conduct of the Ames test and conversant with the physical and chemical properties of petroleum products.
